There are many other wikis related to the foundation, but these are mostly smaller projects. They include the Wikimedia Foundation wiki, the MediaWiki wiki, the Test Wikipedia, the Wikimedia Incubator, Bugzilla, and the Wikimania wiki.

The foundation's creation was officially announced by Wikipedia co-founder[4][5] Jimmy Wales, who was running Wikipedia within his company Bomis, on June 20, 2003.

The foundation gets most of its funds from donations, as it is a nonprofit. It also looks for grants. Some companies have helped Wikimedia by giving free computer hardware, and by hosting servers. Since people can write the wikis, Wikimedia projects are free to use. Funds are used to run computer servers and to pay staff. The Foundation had 700 employees in 2023.

In 2013, Sue Gardner was the executive director.[6]

In 2015, Patricio Lorente was the Chair of the Wikimedia Foundation Board.[7]

In 2016, Katherine Maher became the executive director.

In 2018, María Sefidari is chair of the board.[2]

In 2022 Maryana Iskander became Chief Executive Officer, replacing Katherine Maher.
